FASTENER FOR TRIMS AND JAMBS.

Specification of Letters Patent.

Patented Aug. 3, 1920.

Application filed. November 20, 1917. SeriaI No. 202,957.

To all whom it may concern:

Be it known that I, WILLIAM K. KETTER- INGHAM, Jr., a citizen of the United States, residing at Jackson, in the county of Hinds and State of Mississippi, have invented certain new and useful Improvements in Fasteners for Trims and Jambs, of which the following is a specification.

This invention relates to a fastening de vice for securing trims and facings to j ambs and walls without the use of nails, or exterior fastening devices, thereby avoiding defacement of the trims and jambs. The device can be used in connection with either windows or doors, and with either brick or wooden buildings.

The invention consists in the novel fea-' tures of construction hereinafter pointed out, shown in the drawings, and set forth in the claim.

In the drawings Figure l is a horizontal section through a window or door jamb and trim, with my fastening devices in place.

Fig. 2 is a front view showing the plates secured to the back of the jamb and the wall, ground or brick, the trim being re moved.

Fig. 3 is a section on the line 33 of Fig. 1.

In the drawings A designates the plaster Wall, E a portion of the casing, ground or brick, according to the construction of the building, C the trim and D the jamb.

These are parts of the building and are shown only to make the use of the invention clear.

The fastening devices consist of four plates, as follows A plate 1 is set into the ground or brick B, and said plate has openings 3 connected by a dove-tailed groove or slot2.

An angled plate l has its flange 5 secured to the back of the jamb D. This plate is also provided with a dovetailed slot 6 with openings 7 at each end. -The slots 2 and 6 run lengthwise of the plates and the open= ings 3 and 7 are designed to receive the heads of screws 11, to be described hereafter. Two of these openings are provided so that the plates 4 will not have to be made in rights and lefts, and so that plate 1 can be placed by the workman with either end down, thereby eliminating loss of time in case it should not be turned just the right way in placing in position, as would be the case if only one opening 3 were provided.

To the back of the trim C are secured plates 8 and said plates carry centrally a threaded sleeve 9 adapted to receive the screw 11. All the plates have suitable openings for retaining screws and are held in place by screws 10.

After the plates have been placed in proper position, the screws 11' are adjusted in the plates 8 and sleeves 9 with their heads projecting and the trim is then fitted into position the heads of screws 11 entering the upper openings 3 and 7 respectively and then drawn downwardly into the slots 2 and 6. Plates 1 and 4 are so set that they will be slightly spaced from plates 8 thus allowing the screws 11 to draw the trim tight to the jamb. Any shrinkage of trim or jamb at any time can be taken up or allowed for by readjustment of the screws 11. The advantages of the device will be obvious to those engaged in building operations.

What I claim-is:

The combination with a wall, j amb and trim, a plate set in the wall and having openings connected by a slot for receiving the head of a screw, an angled plate one member of which is secured to the back of thejamb and the other of which is slotted with screw-head receiving openings at the ends of the slot, and screw carrying plates secured to the back of the trim, the screws carried by said plates having projecting heads adapted to engage the slots respectively of the, first mentioned plates.

In testimony whereof I aflix my signature.
